... Ordering number : ENA0596 LA6541NH Overview The LA6541NH is a four-channel driver IC for CD players and recorders (four BTL amplifier channels). Functions • Four BTL connection power amplifier channels • max 0.7A • Built-in level shifters • Muting circuit (on/off control of all outputs) (This circuit applies to the BTL amplifier circuits. It does not control operation of the regulator.) • ...
